i have a 79 puch maxi.

70cc k star

3 shoe clutch with lightened clutch plate

treats cdi adventure pack

19mm dellorto race carb

re sealed the case halfs

Got it to fire twice but the second time covered the air port on the carb and ever since it wont fire.

i advanced the stater all the way.

another issue im having is when pulling the clutch lever some times it will catch and other times it will slip and im not to certain why its doing this.

Any sort of advice or input on this situation would be extremely helpful.

ive ran out of ideas

sometimes you got to dremel the slots I hear

Time at 17 degrees not just full advance

Your jetting is off too

You got to tune your idle circuit first before low, mid and full throttle circuits

Google phbg tuning

To high of compression on head

I'm sure you didn't mod the head for less compression

Your never gonna get your bike running good

1 ) not timed correctly

2) squish/compression not correct/not set

3) carb not set up with with correct jets, slides and needles

19 mm race carbs have 4 stroke parts.

If you want to run you bike this summer

lose the race carb and get a 14-15 mm bing after you get it timed

I have a 42 idle and 67 main and it has the w-9 needle in it but it won't start even with spray. But anyone have any idea why my clutch only catches some times and why it slips
